Half-quadratic regularization for MRI image restoration


We consider the reconstruction of MRI images by minimizing regularized cost-functions. To accelerate the computation of the estimate, two forms of half-quadratic regularization, multiplicative and additive, are often used. In [13], we have compared both theoretically and experimentally the efficiency of these two forms using one-dimensional signals. The… (More)
